Delta loop 4NEC2 model

I'd like to post a full parametric 4NEC2 model of a single element (just for now) delta loop antenna which includes a gamma match. If you run the optimizer for example one can find the minimum SWR and/or the resonance condition (min Xin) by playing with antenna perimeter, wire diameter, pigtails parasitic elements, gamma rod length or spacing as well as the gamma capacitance.
